Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™

processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A for easy CPU installation. When you are installing the CPU, make

sure the CPU has a heat sink and a cooling fan attached on the top to prevent
overheating. If you do not find the heat sink and cooling fan, contact your

dealer to purchase and install them before turning on the computer.

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 1 4

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 14
= 1.4 GHz

WARNING! Thermal Issue for CPU

As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements.

AMD Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires a LARGER heatsink and fan. You also need to add thermal
grease between the CPU and heatsink to improve heat dissipation. Then, make
sure that the CPU and heatsink are securely fastened and in good contact with
each other. These are needed to prevent damaging the processor and ensuring
reliable operation. If you want to get more information on the proper cooling,
you can visit AMD’s website for reference.

CPU Installation Procedures for Socket 462

1. Please turn off the power and

unplug the power cord before
installing the CPU.

Open Lever

2. Pull the lever sideways away

from the socket. Make sure
to raise the lever up to a 90­degree angle.

3. Look for the gold arrow. The
gold arrow should point to­wards the lever pivot. The
CPU can only fit in the correct
orientation.

4. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket and can not be seen.
Please note that any violation
of the correct installation
procedures may cause
permanent damages to your
mainboard.

5. Press the CPU down firmly into

the socket and close the lever.
As the CPU is likely to move
while the lever is being closed,
always close the lever with
your fingers pressing tightly
on top of the CPU to make sure
the CPU is properly and
completely embedded into the
socket.

CPU Clock Frequency Selection through BIOS

The hardware configuration for CPU clock frequency of the motherboard
is set to 100MHz by default. Therefore, to make a 133MHz CPU run at 133MHz
when it is installed on the board, you have to adjust the CPU clock frequency
in the BIOS setup utility.

To set the clock frequency for the installed CPU, refer to Frequency/
Voltage Control in Chapter 3. BIOS Setup.

MSI Reminds Y ou...

Overheating

Overheating will seriously damage the CPU and system, al­ways make sure the cooling fan can work properly to protect
the CPU from overheating.

Replacing the CPU

While replacing the CPU, always turn off the ATX power sup­ply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

Overclocking

This motherboard is designed to support overclocking.
However, please make sure your components are able to toler­ate such abnormal setting, while doing overclocking. Any at­tempt to operate beyond product specifications is not
recommended. We do not guarantee the damages or risks

caused by inadequate operation or beyond product
specifications.

Hardware Setup

Memory

The mainboard provides 3 slots for 184-pin DDR SDRAM DIMM (Double
In-Line Memory Module) modules and supports the memory size up to 3GB.
Y ou can install PC2700/DDR333, PC2100/DDR266 or PC1600/DDR200 modules
on the DDR DIMM slots.

DDR DIMM Slots

(DDR 1~3)

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod­ules rather than 168-pin DIMM modules used by SDR SDRAM. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

2-7

MS-6712 ATX Mainboard

DIMM Module Combination

Install at least one DIMM module on the slots. You can install either
single- or double-sided modules in any order to meet your own needs.

Memory modules can be installed in any combination as follows:

Slot Memory Module Total Memory

DIMM 1 S/D 64MB~1GB
(Bank 0 & 1)
DIMM 2 S/D 64MB~1GB
(Bank 2 & 3)
DIMM 3 S/D 64MB~1GB
(Bank 4 & 5)

Maximum System Memory Suppported 64MB~3GB

S: Single Side D: Double Side

Installing DDR Modules

1. The DDR DIMM has only one notch on the center of module. The module

will only fit in the right orientation.

2. Insert the DIMM memory module vertically into the DIMM slot. Then

push it in until the golden finger on the memory module is deeply inserted
in the socket.

3. The plastic clip at each side of the DIMM slot will automatically close.

BIOS Setup

Frequency/Voltage Control

Use this menu to specify your settings for frequency/voltage control.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec­trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, select one of the options for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking
because even a slight jitter can introduce a temporary boost in clockspeed
which may just cause your overclocked processor to lock up. Available options:

Enabled, Disabled.

CPU FSB Clock

This item allows you to select the CPU Front Side Bus clock frequency (in
MHz) and overclock the processor by adjusting the FSB clock to a higher
frequency. First set SW1 and SW2 to the selected CPU frequency and then
select the overclocking frequency accordingly. Options are:

CPU FSB 100MHz Overclocking 100~167MHz
CPU FSB 133MHz Overclocking 133~200MHz
CPU FSB 166MHz Overclocking 166~233MHz

CPU Ratio/Vcore (V)

The settings are used to adjust the CPU clock multiplier (ratio) and CPU
corevoltage (Vcore). These settings offer users a tool to overclock the system.

MSI Reminds Y ou...

Changing CPU Ratio/Vcore could result in the instability of the
system; therefore, it is NOT recommended to change the default
setting for long-term usage.

DDR V oltage (V)

Adjusting the DDR voltage can increase the DDR speed. Any changes made
to this setting may cause a stability issue, so changing the DDR voltage for
long-term purpose is NOT recommended.

T ermination Vol (V)

The settings are used to adjust the termination voltage. Setting options: Auto,

1.27, 1.29.

AGP V oltage (V)

AGP voltage is adjustable in the field, allowing you to increase the perfor­mance of your AGP display card when overclocking, but the stability may be
affected. Setting options: Auto, 1.6, 1.7, 1.8.

Set Supervisor/User Password

When you select this function, a message as below will appear on the screen:

Type the password, up to six characters in length, and press <Enter>. The
password typed now will replace any previously set password from CMOS
memory. You will be prompted to confirm the password. Retype the password
and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.

T o clear a set password, just press <Enter> when you are prompted to enter the
password. A message will show up confirming the password will be disabled.
Once the password is disabled, the system will boot and you can enter Setup
without entering any password.

When a password has been set, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any
part of your system configuration.

Additionally, when a password is enabled, you can also have AMIBIOS to
request a password each time the system is booted. This would prevent unau­thorized use of your computer. The setting to determine when the password
prompt is required is the P ASSWORD CHECK option of the ADVANCED BIOS
FEATURES menu. If the PASSWORD CHECK option is set to Always, the
password is required both at boot and at entry to Setup. If set to Setup, pass­word prompt only occurs when you try to enter Setup.
